BACKGROUND: There is widely known that breast-feeding has protective effect to atopic dermatitis in childhood, particularly less than 2 years old. But, epidemiological evidence for a role of breast-feeding on risk of atopic dermatitis is inconclusive in Korea. The objective of this study was to investigate the associations between breast feeding and risk of atopic dermatitis in early childhood in Korea.

METHODS: We combined the fourth and fifth Korea National Health and Nutrition Examination Survey data collected from 2007 to 2012 and analyzed 2,015 children who had been surveyed in regards to breastfeeding. Multivariate regression analysis was used to identify association among the following variables: presence of atopic dermatitis by diagnosed doctors, feeding types and duration of breast-feeding, previous history of parents’ allergic diseases.

RESULTS: The peak prevalence of exclusive breast-feeding and atopic dermatitis was 35.5% in 2009 and 17.7% in 2008, respectively. Since then, the prevalence of exclusive breast-feeding and atopic dermatitis annually decreased to 26.2% and 8.9% in 2012, respectively. No measurable statistically significant relationship was observed among breast-feeding, formula-feeding, duration of breast-feeding and risk of atopic dermatitis in the multivariate analysis except previous history of parents’ allergic diseases.

CONCLUSIONS: The present study showed no statistically significant relationship between breast-feeding and the risk of atopic dermatitis in early childhood inKorean children. National prospective study is needed to clarify the role of breast-feeding in development of atopic dermatitis.
